reaction mass of: trisodium 3-(5-(2,6-difluoropyrimidin-4-ylamino)-2-sulfonatophenylazo)-5-(4-fluoro-6-morpholin-4-yl-1,3,5-triazin-2-ylamino)-4-hydroxy-2,7-naphthalenedisulfonate; trisodium 3-(5-(4,6-difluoropyrimidin-2-ylamino)-2-sulfonatophenylazo)-5-(4-fluoro-6-morpholin-4-yl-1,3,5-triazin-2-ylamino)-4-hydroxy-2,7-naphthalenedisulfonate
EC number: 436-890-6 | CAS number: -

Description of key information
A study was performed according to OECD guideline 116 and in compliance with GLP. The fat solubility of the test substance was
less than 0.005 mg in 100 g fat at 37°C, i.e. below the detection limit of the lowest calibration standard.
Key value for chemical safety assessment
- Solubility in mg/100g standard fat:
- 0
- At the temperature of:
- 37 °C
Additional information
A study was performed to determine the fat solubility of the substance Reactive Red FC 73270. Mixtures of the test substance and fat were stirred for different times (3 or 27 h) and at different temperatures (30, 50 and 37 °C). The saturated liquid phase was separated from the undissolved test substance by filtration, mixed with hexane and extracted three times with water. The aqueous phases were combined and UV/Vis absorption spectra were recorded between 200 and 800 nm. The test substance showed fat solubility of < 0.005 mg in 100 g fat at 37 °C (i.e. below the detection limit).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
